Java-buildpack: Le JBP prend-il en charge Spring Boot 2.0 ?

Nous ne l'avons pas encore testé, mais étant donné que la façon dont il fonctionne ( java -jar ) n'a pas changé, je n'ai aucune raison de croire que ce n'est pas le cas.

J'ai en fait un problème avec le M3 actuel. Mais cela ne se produit que lorsque MongoDB est utilisé. Cloud Foundry essaie de reconfigurer la connexion MongoDB et se heurte à un NoSuchMethodError .

Autant que je sache, cela est dû à des changements de rupture dans la dépendance spring-data-mongo .

Le programme d'installation est une application Spring Boot 2.0.0.M3 de base avec des démarreurs pour :

• actionneur
• data-mongo
• la toile
• etc.

Le projet est disponible ici :

Oui, c'est un problème de reconfiguration automatique. Nous dépendons d'une version de Spring Cloud Connectors qui n'est peut-être pas prête pour la mise à niveau de la version majeure vers Spring Data. @scottfrederick en êtes-vous conscient et tout ce que je dois faire est de commencer à utiliser une nouvelle version des connecteurs Spring Cloud ?

J'ai mis à jour nos applications de test Java vers Boot 2.0 . Sur la base de ce travail, la seule chose qui semble poser problème est que la reconfiguration automatique de Spring Data Mongo semble être interrompue (modifications de l'API). Je vais laisser ce problème ouvert comme indicateur de cela, puis le fermer une fois que nous aurons un correctif en place.

Une estimation quand cela sera disponible? Aussi : existe-t-il des solutions de contournement applicables pour le moment ?

Nous sommes sur le point de livrer, mais nous attendons toujours que @scottfrederick publie une version de Spring Cloud Connectors. Nous avons effectué un travail important pour simplifier la reconfiguration automatique et la mettre à niveau pour utiliser Spring Cloud Connectors 2.x. Dans le cadre de ce travail, nous avons soumis un PR pour nous assurer que tous les types configurés étaient compatibles à la fois avec Boot 1.x et Boot 2.x. Cela a été inclus mais est toujours en cours de test. Une fois qu'il sera publié, nous le consommerons et obtiendrons une nouvelle version de la reconfiguration automatique dans la nature.

Il n'y a pas vraiment besoin de solution de contournement car tout, sauf la reconfiguration automatique de MongoDB, fonctionne comme prévu aujourd'hui. Si vous essayez d'effectuer une reconfiguration automatique de MongoDB, il n'y a pas d'autre solution que de configurer explicitement votre application pour utiliser le service (ce que vous devriez faire de toute façon ; la reconfiguration automatique n'est pas un bon choix pour les systèmes de production).
